Thermal sensor in hard disk replacement

I've bought a western digital 1tb green HD, and the ifix guide for the HD replacement, about "thermal sensor" write down: "During reassembly, be sure that the thermal sensor connector is connected to set of pins closest to the SATA connectors". The Hitachi has two pins arranged like this:

but the Western Digital has 8 pins arranged like this:

I've connected the thermal cable to the set of pins closest to the sata connectors ... in this way:

If the original poster could add how thery fixed th eproblem i'd be grateful. I have the same problem.

I changed a 500g Seagate to a 1G seagate...and now my fan is running on full..wondering if i need to reverse the cable or simply modify a setting.

Update

Thanks Dan.

I opened up the mac again and could not find any cable that I might have missed. I also called seagate ( the 500g i removed was a barracuda 7200...as was Th.e1TB i installed) and they have NO idea that is compatible with mac or if there is a setting that could be adjusted.

Rather than order a cable set and have to go in deeper on the board - i downloaded HDD Fan control....works great.

Depending on the model you have you should find an external sensor mooted on the HD case. If not then you have one that uses the internal sensor. We use this kit from OWC 27" iMac kit. This by-passes the internal sensor in the new HD (if it has one) to an external sensor. This allows you to us any HD. If you got one of the very new HD's that support Apples internal sensor you should be OK.
